How to Downgrade the Kernel in Linux
Linux lives and dies by the kernel. If you’re familiar with how GNU/Linux works, Linux is the kernel. Everything else is just tools that interface with it. These tools let you get actual work done, but they couldn’t do a thing without the kernel.
The kernel of an operating system is kind of like your cardiovascular system. You tend to forget about it until something goes wrong. It isn’t all that often, but kernel upgrades can and do go wrong. When the updated kernel won’t let you use your computer, it’s time to downgrade.
The good news if you’ve recently updated your kernel is that this process almost never gets rid of the old kernel. The only case where that may happen is if you immediately uninstalled the older kernel, which isn’t a great idea.
To boot into an older computer, you’ll need to restart your computer. When the computer loads GRUB, you may need to hit a key in order to select non-standard options. On some systems, the older kernels will be shown here, while on Ubuntu you’ll need to select “Advanced options for Ubuntu” to find older kernels.
Once you select the older kernel, you’ll boot into your system. Everything should work as it used to. If you’re still having trouble, the kernel may not be the issue.
Remove the Problem Kernel
If you’ve booted into your computer and everything is working as intended, the upgraded kernel is likely the problem. You could technically just do this every time you boot your computer, but it makes more sense to remove the problematic kernel.
You can do this using your distribution’s package management tools. This is going to differ based on the system you’re using. You’ll also need to know the version of the kernel you want to remove. This can be found during bootup at the GRUB screen. For Ubuntu and other apt-based distributions, you can use a command like the following:
You’ll need to replace VERSION above with the exact version number of the problem kernel you’re looking to remove. If you just wish to hold them back for a time, you can use the following command:
sudoapt-mark hold linux-image-generic linux-headers-generic
Avoiding Future Issues
One of the easiest ways to avoid this type of problem is to avoid updating right away. This will give you a chance to see if any reports of users having kernel trouble will pop up. You should especially keep an eye out for users with similar hardware to you.
If stability is key to you, you can also opt to use LTS distributions. These update less frequently aside from security updates. This means you can count on these being more stable than your average distro.Conclusion
While downgrading is the easiest way to deal with kernel-related issues, it isn’t the only way. Sometimes it’s not possible either. Maybe the updates kernel includes hardware support you desperately need, while the bug is related to hardware you don’t even use.
How are Cloud Storage, Cloud Backup, and Cloud Sync Different Tracey Rosenberger 15th Apr 2018 How Things Work 2 Comments Share Tweet Email You hear the words tossed around all the time – Cloud storage, Cloud backup, Cloud sync. What are they? Are they different and do you need one? Cloud storage means an offsite server owned by a hosting company where you store your data . If you’ve had a personal computer crash, and you lost all your data, you understand how frustrating it is. Cloud storage makes it possible for you to recover your files even if your computer has breathed its last breath. Cloud Storage There are three types of cloud storage: public, private, and hybrid. In public cloud storage, global data centers store your data, and you pay based on how much storage ...
Debian vs. Ubuntu: The Similarities, Differences and Which One You Should Use By Alexandru Andrei – Posted on Jul 9, 2019 in Linux Ubuntu received a lot of love in its earlier releases. It made many seemingly complicated operations, easier for beginners just coming into the world of Linux-based distributions. But around the time the Unity interface was launched, it started to get some hate, too. Objectively speaking, the interface was not good or bad, it did its job well. But it did it differently than what most people were used to. Then, some other changes, like inserting ads in the launch menu and changing the interface once again to Gnome, made some users dislike the distro even more and people began to look for alternatives, with one of them being Debian. Since Ubuntu is created from Debian, the two are very similar at the core. However, with the changes Canonical made to Debian to create Ubuntu, there are also a lot of differences, s...
AutoCAD is a flagship product by Autodesk, the drafting industry’s juggernaut, designed to help its users with product or building design, manufacturing planning, construction and civil infrastructure. The sleek, three-dimensional, computer-aided design software is fully-featured but costs a lot more than other programs that match its capabilities. Since 1982, when it was made available, AutoCAD’s wide range of features and versatility for use in several industries make it the go-to product for professionals, students, and hobbyists alike. However, Autodesk no longer offers perpetual licensing for AutoCAD and switched to a subscription-based licensing instead, which forces users to seek out alternatives. In the long run it may be costlier to make the switch, though for CAD pros who aren’t limited budget-wise, paying more than $1200 may seem worthwhile. If you’re an average student or hobbyist working on a lean budget, you don’t have to always pick AutoCAD. There are so...
